Vocabulary for AP Human Geography Chapter 1: Maps and Spatial Concepts and Geospatial Technologies
Core Map Types
Thematic Map
Designed to tell a story about a specific theme or topic, like population density or climate.
Examples include:
Choropleth maps (use colors to show data)
Dot distribution maps (show frequency of a variable)
Proportional symbol maps (size of symbols indicates the value)
Isoline maps (connect points of equal value)
Reference Map
Used for navigation and to locate geographic features.
Examples include:
Physical maps (show landforms like mountains)
Political maps (show boundaries between areas)
Road maps
Local Map
Shows detailed information for a small area like a neighborhood or city block.
Global Map
Represents large areas of the world, useful for understanding broad patterns like trade or climate.
Measures of Distance and Direction
Absolute Distance
The exact measurement between two points (e.g., 10 miles).
This distance remains the same regardless of how you travel.
Relative Distance
Describes how far apart places are based on time or cost (e.g., it takes 2 hours to drive 100 miles).
Absolute Direction
Fixed directions like North, South, East, and West.
Relative Direction
Directions based on perspective or common landmarks (e.g., "go left at the school").
Location Concepts
Absolute Location
The precise spot on the Earth, often found using coordinates (e.g., 40.7128° N, 74.0060° W).
Relative Location
Where something is in relation to other things (e.g., "next to the park").
Cartographic Tools and Methods
Elevation
Height of a place above sea level, often shown with contour lines on maps.
Map Projection
Method for showing the Earth's curved surface on a flat map, which can distort sizes or shapes.
Geographic Information and Technology
Geographic Information Systems (GIS)
Technology that allows the layering of different types of geographic data to analyze spatial relationships.
Navigation Systems
Use satellites to find exact locations and give directions.
Remote Sensing
Collecting data about the Earth from satellites or aircraft, which helps analyze environmental changes without being on-site.
Landscape Analysts
Study how humans shape and alter their environment, and the interaction between culture and nature.
Spatial Concepts and Interaction
Distance Decay
The idea that interaction decreases as distance between places increases.
Time-Space Compression
The perception that distance feels shorter due to technology making travel and communication easier.
